QPECIFICATION forming part of Letters Patent No. 341,712,:1ated May 11, 1886.

Application filed February 2'7, 1886. Serial No, 1953;493. (No modeLl To a, whom it may concern.-

Be it known that I, WILLIAM C. WiLson, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Vaporizers for Medicinal Purposes, of which the following is a specification, reference being bad therein to the accompanying drawings.

My invention relates to a portable device to be carried in the pocket, which consists of a vaporizing device to be applied to the body for the purpose of stimulating the blood-ves sels or nerves to remo e congestion, and to increase and render more active the circulation at the point where the device is applied.

The main object of the invention is to render the application of remedial agencies more easy and convenient, since the device is small and compact, may be carried constantly on the person, and may be applied as frequently as is necessary by the patient himself.

For a full comprehension. of my invention and the manner of using it, reference must be made to the accompanying drawings, in which- Figure 1 is a side elevation of the vaporizer. Fig. 2 is an end view. Fig. 3 is a vertical section. Fig. 4 is a horizontal section.

A represents the cylindrical body or shell, enlarged at one end, preferably by spinning, to form a circular eye cap, -1, which may be provided with a beaded edge, 2, as shown, A partition, 3, closes the end of the shell at the bottom of the cye'cap, in which partition is a central perfbration, 4c. The end of the shell is diminished in size, as shown, and has a perforation, 5, by which air may enter to the interior of the shell. This opening, when the instrument is not in use, is closed by a screwcap, 6, having a milled edge to facilitate its removal.

\Vithin the shell A, I secure a cylinder of perforated sheet metal or wire-gauze, C, leaving an unobstructed passage through the center, and forming a space between such cylinder and the inside of the shell of sufficient size to contain an absorbent packing, D, which may be saturated with any volatile substance of a medical character, that will by evaporation and consequent application to any par ticular part of the body stimulate the nerves and blood'vessels, and produce upon them a beneficial result. The perforation 3 at the bottom of the eye'cap is closed by a screw-cap, 8, having a projection, 9, which enables it to be conveniently seized.

In applying the instrument, for instance to the eye, for the treatment of which it is particularly intended, the screw caps are removed from both ends of the shell and the eye cap is applied to the closed eye in the manner of a watch-makers glass. At the same time the pressure of the air through the opening in the top of the shell will produce a certain amount of evaporation of the liquid absorbed by the packing, and the vapor will be discharged through the opening in the eye-cap directly against the eye.

I do not confine myself to the use of any particular therapeutic agent, because there are many solutions of a medicinal character well known to physicians with which the instrument might be charged.

The instrument may also be conveniently used as an inhaler by removing the cap 6 and cap 8, the unobstructed passage through the center permitting the air to pass freely through.

The advantage of my device is that it affords a very simple means whereby the patient may have constantly ready for self-application the remedies which might otherwise have to be applied with more or less difficnlt-y and personal inconvenience.

Having thus described my invention, I claim 1. A vaporizer for medicinal purposes, consisting of a body, A, an internal perforated cylinder, an absorbent packing surrounding the internal cylinder, and openings in both ends of the body A registering with theinternal cylinder and having removable caps or covers, substantially as described.

2. The body A, having the flanged eye-cap, 9

the central perforated cylinder,O, the absorbent packing D, surrounding the cylinder, and openings in the body A at each end thereof, having removable caps or covers, substantially as described.

In testimony whereof I have affixed my signature in presence of two witnesses.
